Abstract

Proposed is a projectile (1) with a plurality of luminous bodies (7), which are eccentrically incorporated in a projectile casing (2) and ignited via at least one delay element (11, 12) per luminous element (7). The transfer of the discharge gases from a Geschossogive (9) to the delay elements (11, 12) by filling elements (8), the center of the projectile (1) form a channel (10) for the discharge gases.

Description

The The invention relates to an ammunition or bullet or the like with several lights for battlefield lighting.

flares for battlefield lighting is either from a weapon, z. B. a mortar, fired (light grenade) or from one Missile dropped as a bomb (light bomb). she consists essentially from a slowly burning pyrotechnic flare (For example, a magnesium compound), from the respective ammunition shell is ejected after a predetermined period and at a parachute glides to the ground. The flare emits during of its descent light in the visible and / or infrared wavelength range and thereby enables target illumination or targeting.

generally known Lightbulbs contain a single luminous element. This is due to a discharge charge after one, the time fuze adjustable time, expelled from the projectile shell. Alternatively, when artillery shots at the output of the ground separated and the submunition on a discharge plate pushed out of the projectile shell. The luminous body is then braked by one or more parachute systems.

A projectile with a payload describes the DE 28 30 224 C2 , The carried payload is a light body with a parachute as a braking system.

A light pot for projectiles, etc. reveals the DE 75 11 529 U1 , This is ejected during flight while igniting the flare from the projectile casing, the flame jet of the parachute floating to the ground luminescent pot exits down from this.

These It is also a luminous body with pyrotechnic Ignition, this has the disadvantage that the pyrotechnic Flare regularly represents a risk because he can inadvertently ignite and explode. In addition, during the burnup can descend release burning parts and fall to earth, something with an increased fire hazard and a hazard of persons and environment as well as with a shortening of the Burning time is connected. Unless the flare for infrared lighting of the battlefield is inevitable by the burnup also emits visible light, which is avoided in itself should. Finally, with the eviction and Salvage associated with pyrotechnic material relative expense large.

From the not pre-published DE 10 2007 048 074.3 is such a light ammunition with ejected from a projectile shell and hanging on a parachute light known. The luminous element consists essentially of a cylindrical housing and a base plate arranged on the housing carrier plate with a plurality of array-like arranged light emitting diodes (LEDs) that illuminate a battlefield and hang on a parachute. The LEDs of the filament are connected via an electronic control device to a power source. In this case, the control device ensures that the power supply of the LEDs takes place only after opening the parachute and only during the subsequent sinking phase of the filament.

adversely is that in case of malfunction of the parachute the battlefield at all not lit. In weather-related situations, for example gusty wind, it can cause lurching or tumbling movements come. These cause shadow movements due to the moving Filament and makes the observation of the battlefield difficult. The actual function of the filament is then only still conditionally given.

at Artillery projectiles is the diameter of the filament also relatively large. As a result, they are also very heavy and cause a big Dimensioning of the parachute. In the case of the floor separation It may cause damage when opening the parachute system come to this.

From the DE 2 103 672 A1 In addition, a multiple charge for lighting a ground surface or a body of water is known. For this purpose, a predetermined number of partial charges, each with a pyrotechnic flare and associated parachute is integrated in a cavity of a body or container. Each partial load is provided with a delay powder charge adapted to each partial load involved. The different partial charges have different delay times, and indeed the partial charge which is pushed out of the container before another has the shorter delay time. It is thereby achieved that a successive drifting of the partial charges from the body or the container takes place in the atmosphere, while the delay times themselves are chosen so that there is a wide scattering of the partial charges in the atmosphere.

Of these, Based on the object of the invention, a light ammunition to show with multiple charge, which does not have the aforementioned disadvantages has more.

The problem is solved by the features of claim 1. Advantageous embodiments are contemplated in the dependent claims.

Of the Invention is based on the idea, also several luminous bodies in to place a projectile or projectile shell, wherein the fall rate reduction systems or braking systems (such as Parachute, etc.) only after a predetermined flight time and a Stabilization and functional by a delay element is done. The delay time of the ignition of individual filament should be chosen differently be. The filaments can be used in all types of Containers or covers, such as artillery shells, be introduced. Patches between the lamps are to be adapted to this, if necessary, the number of luminous elements. The Patches or filling elements preferably form in the middle a ignition channel for the ignition the filament. Due to the eccentric bearing of the Distribute luminaires within the projectile shells the luminaries after ejection far cheaper as the well-known Einlicht body or Vielellobeleuchter. This also has the consequence that the luminous body Less hit or damaged by the floor can.

The Shape of the luminous body allows to as Modules for different floors to act. By the Distribution of several luminaires in several levels in the floor is a better illumination by the same time achieved luminous luminous body.

are the luminaries in two or more levels within integrated, it makes sense, for example, the delay times to distinguish the luminous element of the planes. by virtue of begin the differently adjustable delay times the lights will then light up at different times. The advantage of this is that when voting the different delays the total illumination time can be extended. In case of malfunction of a fall rate reduction system or the ignition remain the other filament in turn capable of functioning.

The Integration of several luminous bodies also has the Advantage that due to the smaller mass and size the speed reduction systems are not so heavily loaded become. It may involve simpler stabilization mechanisms which, in turn, cause the swirl and velocity loads greatly reducing the use of simple fall systems can. A related to the weight reduction Wettertechnische Dependence is abolished by the fact that strong Gusts the associated tumbling movements through all Luminous bodies are executed - the ground to be illuminated from several directions even when tumbling is illuminated.

The Use of non-spin stabilized projectiles is also possible. Here are the filaments through the Ejection charge via the ignition channel radially accelerated away from the projectile shell.

in principle is made possible by the integration of an ignition channel, that only one ignition device for the several Luminaires is needed.

One Another advantage is that with these luminaires with sufficient illumination, an unwanted dazzling avoided can be.

Based an embodiment with drawing, the invention be explained in more detail.

It shows:

1 a side sectional view of a luminous body contained bullet,

2 a sectional view of a filament 1 .

3 a scenario for deploying the luminous bodies.

In 1 is a projectile 1 represented, which consists of a projectile shell 2 , a discharge charge 3 and a discharge plate composed. Next to a projectile fuze 5 and a storey floor 6 are on the floor 1 furthermore, luminous body 7 and filling elements 8th , The luminous bodies 7 are here in two levels 14 . 15 brought in. In the example shown are eight luminous bodies 7 in the floor 1 involved. The filling elements 8th preferably form in the center of the projectile 1 a channel 10 for the exhaust gases via the delay elements 11 . 12 the filament 7 be lit.

The single luminous body 7 itself consists of a shell 18 , in which, for example, a pyrotechnic flare 19 , and in this case preferably two delay elements 11 . 12 or a two-stage delay element, an ejection system 16 . 22 as well as a parachute 17 are housed ( 2 ). On the outer shell is a stabilizing element 13 , which is not absolutely necessary.

About the projectile fuze 5 the time is set after which the initiation of the ejection charge 3 should be done. About the height direction of Weapon (not shown), the selection of the charge and setting of the projectile fuse 5 the range is determined in which the battlefield lighting is to take place.

At the end of the detonation period, the projectile fuze initiates 5 the ejection charge 3 , By the burning of the ejection charge 3 is in the projectile shell 2 in the area of the projectile 9 creates a pressure on the ejector plate 4 acts and over the luminous bodies 7 and the filling elements 8th on the floor of the storey 6 is transmitted. With reaching the necessary pressure the soil shanks 6 off and the filaments 7 as well as the filling elements 8th be through the ejection plate from the bullet casing 2 ejected to the rear. At about the same time, while the pressure in the Geschossogive 9 builds up, the combustion gases are on the channel 10 to the delay elements 11 . 12 the filament 7 directed. The transmission from the channel 10 to the delay elements 11 . 12 takes place via firing holes 23 in the filling elements 8th ,

After ejection of the luminous bodies 7 from the projectile shell 2 the luminous bodies are distributed 7 for example due to the projectile spin. In this case, stabilization elements 13 at the filament 7 reduces the spin as well as the speed and ensures a defined case. The stabilizing elements 13 on the luminaires 7 can by the eigendrall the luminous body 7 be spread. Other possibilities are also given.

After expiration of the delay time, for example, by the first delay element 11 is adjustable, a release screw 16 or the like separately and a cover 22 repelled. This can now be the parachute 17 on the respective luminous body 7 unfold.

After the time passed by the second delay element 12 is set, the actual pyrotechnic flares 19 inflamed. The transit times of the second delay elements 12 differ in the luminous bodies 7 the levels 14 . 15 , Depending on the design of the projectile 1 the light sets begin 7 the level 14 respectively. 15 burn down first and the battlefield 20 to illuminate. By the scatter 21 the filament 7 after ejection from the projectile shell 2 is the illuminated battlefield 20 larger than the one by a single luminous element 7 illuminated area 24 , The delay elements 12 the filament 7 the different levels 14 . 15 are so coordinated that the light sets 19 the level 14 . 15 be ignited before the filament 7 the other level start to shine. This delay can increase the total illumination time compared to conventional lighting systems.

It is understood that instead of the pyrotechnic flare 19 also LEDs can be used. Here could then be a double-stage delay device ( 11 . 12 ) are omitted in the form described, since a simple is sufficient.
